TEHRAN (NIPNA) -- The Research Institute of Petroleum Industry (RIPI) has successfully developed the technical know-how for production of ultrafiltration membrane at semi-industrial level.
RIPI, joined by
the Petrochemical Research and Technology Company (PRTC), has manufactured a
system for formulation of ultrafiltration membrane.
The system can
produce 15 meters of 50-cm wide membrane every minute.
(UF) is a variety of membrane filtration in which forces like pressure or
concentration gradients lead to a separation through a semipermeable
solids and solutes of high molecular weight are retained in the so-called
retentate, while water and low molecular weight solutes pass through the
membrane in the permeate (filtrate).
process is used in industry and research for purifying and concentrating
macromolecular (103 - 106 Da) solutions, especially protein solutions.
selectivity, low energy consumption, low installation and operation costs are
some of the features of this new UF system.
